Made some progress on this unknown 1 tuber. I've restored the cardboard cabinet to a level that I think is acceptable (plus I've run out of further ideas).

I finished cleaning up the gold section, then started working on the areas where the fabric covering the cardboard had frayed, been torn, or was simply missing. Mostly that was in the corners and high spots where it would get worn. I used some Weldbond Universal Adhesive to consolidate the frayed fibers of the fabric so they would not continue to fray. For smaller areas it also served to fill in some of the missing fabric. If there was a larger gap, I used some Timbermate wood filler. After the adhesive and wood filler dried, I did the touch up painting. There was a small amount of gluing down some loose edges of the fabric and it was all followed by two coats of a furniture wax.

The other thing I was able to do was take the fixed coil off the radio to get a better look at it. It turns out there are two separate coils on the fixed tube. One of the coils has what I think must be a missing connection. I was able to get measurements on both coils but the connection I've labelled #4 is just a little stub of a wire found in the center of the fixed tube. I don't know where it might have been connected (if at all). I've redrawn the schematic to reflect the new info along with a diagram and photo of the coil out of the radio. Hoping someone can make sense out of it....
